I Patented To all whom it may concern;

Be it known that I, Cnannns Fmxors Jnnnms, citizen of the United States, re-

siding at Washington, in the District of,

Columbia, have "invented certain new and useful Improvements in Machines for Inserting Closures in Receptacles, of which the following is a specification, reference beinghad therein to the accompanying draw is a plan view of a die and portions of its supportin frame. Fig. 2 is a section on the line 2-2,% ig. 1. Fig. 3 is a partial sgction on the line 33, Fig. 1. Fi 4 isa bottom plan view of a portion of the die and certain co-acting parts. Fig. 5 is a detail side.

I .view, partly in section, showing parts seen also in Fig. 4. Fig. 6 is a bottom plan view of a sliding bar seen also in Figs. 4 and 5. Fig. 7 is a view showin the end ofthe same bar with the part in w ich it slides appear ing in section. Fig. 8 is a cross-sectional view of parts shown in side view in Fig. 5.

In these figures, A represents a portlon of a frame supporting the working parts of the machine. The disks are cut from a stock-strip G bythe hollow reciprocatin plun er E co-acting with a fixed die H an are then formed by a second reciprocating plunger F co-acting with a die H, yieldlngly supported by springs H which allow it to descend until it meets a stop H", after which the plunger F in continuing to advan'ce inserts the closure in the bottle D.

the machine runs at high speed. The entire structure thus far set forth is without novelty herein claimed.

As above suggested, with certain kinds of stock, the closure sometimes rises with the descri At two or more points on .the lower side' of the die H I form'ways for radially slid-' withdraw plunger tellingwith it bottle, but the bottleis arrested when it meets the die H and falls by gravity, .0 that at very slow speed harm may not rflnlt. But at high speed, decre coat the interval between the withdrawn of t e plan-- gor -and the advance-of a bottle, by a belt or chain, is necessarily very slight, and there is not time for the bottle to rise to the and agam fall by tgravit I therefore prevent such giant 0 the tie by devices to be Apr. 5, 1m.

ing bars I, which,'when the dieis at the upper limit of its pa th, project inward nearly to the path of the msertmg' plunger, and at their opposite ends pro'ect outward beyond the die. This outwardl projecting end engages a fixed downwardl wardly inclined guide bar J slidin thereon as they descend with the die and bemg therey and outby drawn outward, so as to clear the bottle,

beforethe latter is reached by the die. As soon as the plunger ushes the closure entirely through the die, into the bottle, thedie is suddenly restored to initial position by its springs and the bars I rising, with it,

are as suddenly shot forward, by the guide bars J, over the margin of theibottle, preventing the latter from rising with the p 1y resist its lateral advance by the belt.

to a narrower support J lying in' parallel position over its middle line, and the outer end of the broader bar I is providedwith a T-shaped oblique slot I, the wider portion to receive the bar J and narrower art to permit it to pass along the support J From the construction itfollows that as the die descends the bar I is carried down with it and is compelled to slide radially outward, by its engagement with'the inclined guide bar J, with the result that when the die reaches the top of the bottle the conical recess in its lower side is unobstructed so that the die both forms the end of the bottle and alines it with the cap-insertin un-. ger into engagement with anything which can materia For convenience, the bar J is fixed j the inclined guide bars J. If, an instant later, the bottle and cap begin to rise with the plunger, the bars arrest them, while the plunger moves on, leaving the bottle free to be advanced laterally-by the belt, which at the same time brings another bottle to moved into and out of the space within the ring, and means whereby the said bars are withdrawn from said space as the die moves from said plane and projected into said space as the die returns.

2. The combination with a s ring supported annular die arranged or limited movement from its normal plane, and provided upon its lower side with walls flaring outward from its central opening, of bars secured to the die and arranged for radial movement with respect to the same, and guiding devices engaging the bars and adapted to force them outward as the die moves from said plane and inward as the die returns.

'3. The combination with the frame, provided with stops for a die, of an annular die arranged to move to and from said stops, springs yielding'ly opposing the dies advance to the stops, radial bars mounted on the die to move radially, and guides engaging the bars and adapted to move them outward as the die descends and force them inward as the die rises.

4. The combination with the spring supported annular die having the conical recess below, of a plunger to co-act with the die in forming and inserting closure disks, radial'bars movable in ways on the lower side of the die, and fixed inclined guides engaging the outer ends of said bars, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
